Correct answer
When the trailer’s MAM exceeds 3,500 kg.
The figure limits the prohibition to trailers whose MAM exceeds 3,500 kg. A two-axle trailer with a MAM of exactly 3,500 kg does not exceed the threshold; “exceeds” is different from “equals or exceeds”. Actual load mass or the lorry’s MAM does not replace trailer MAM for this sign. Single-axle trailers are exempt; other restrictions still apply.
